CHRISTIAN WILDHABER, OF NEW YORK, N. Y.

SIFTING .AND SEPARATING DEVICE.

Application 1ed January 30, 1919.

To all whom t may concern.'

Be it known that T, CHRISTIAN WILD- HABER, a citizen of the Swiss Federal Republic, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful improvements in Sifting and Separating Devices, of which the following is a specification. j

The present invention relates to a siftingand separating device, especially adapted for use of tailors, clothiers, etc.

in tailoring and clothing-producing establishments the sweepings consist mainly of cloth pieces, buttons, snap fasteners, hooks and eyes, beads, pins, needles, etc. It has beenV found heretofore that, in order to properly separate and assort these articles, considerable time and labor is needed, making the process so expensive that in most establishments the sweepings, or at least part thereof, are thrown away instead of being recovered.

The main object of the present invention is to produce a simple and comparatively inexpensive sifting and se )arating apparatus, whereby the sweepings are with little labor and conveniently assorted, and dust and other foreign matter separated therefrom.

Another object of the invention is to pro duce a device of the character mentioned which is capable of manufacture on a commercial scale or, in other words, one which is not so difficult to construct as to be beyond the reasonable cost of such a contrivance.

lith these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which:

Figure 1 is a vertical longitudinal section taken through an apparatus constructed in Specification of Letters Patent.

Patented Feb. 17, 1920.

serial No. 274,037.

accordance with the present invention; Fig. 2 is a section taken on line 2 2 of Fig. 1; Fig. 3 is a top elevation thereof, certain parts being removed in order to more clearly show the construction; Fig. t is a perspective view of a suspending element for the shifting means of the apparatus; and nig. 5 is a perspective view of one of the sifters, looking from the bottom upward.

1n the drawings, the numeral 10 indicates a receptacle, -in the form of a'box, that is made up of sides 11, ends 12, a bottom 13 and a. cover 1-1. This box may be of any suitable material, for instance wood, and. of a size according to the requirements. The cover 14 is preferably hinged, as shown at 15, to the box body and is provided with a suitable locking means 16, to hold it in closed position. In order to prevent dust from escaping from the box, as the sweepings are being assorted, packing strips 1T are attached to the sides and ends of the box body adjacent to the cover.

lVithin'the box is disposed a swinging frame 1S, upon which are mounted the sifting and asserting devices. This fra-me is preferably of quadrangular cross-section and made up of bars 19, for instance angleirons, the horizontal flanges 2() of which serve as a support for the lowermost of the sifting and assorting devices, while the vertical fianges 21 of the same hold the said sifting and assorting device in position. The frame 1S is mounted upon suspending means 22, for instance U-shaped bars, the upper ends of which are bent outward, as shown at 23, and oscillatably mounted in the sides 11 of the box. To one of these U-shaped bars is secured a rod 24, which extends through an aperture 25 in one of the ends 12 of the box and is provided outside of the box with a handle 26. Upon the frame 18 is mounted a plurality of sifting devices 27, which are each in the form of a sieve. Each of these sieves comprises a frame 28, for instance of wood, with a screen 29 in the bottom, said screen being made, preferably, of wire. These sieves are placed one on top of another and are held in proper position relative to each other by stops 30. To each sieve frame 28 there is att-ached a plurality of stops 30, in the form of small plates, that are secured to the frame near its lower edges and project below the same. Those portions of the plates, which project below a frame, abut against the outer surface of the next sieve frame in the series.

The wire screens of the several sieves are of gradually decreasing sizes of meshfrom the top sieve to the bottom sieve or, in other words, the screen of the top sieve is of the coarsest Vmesh and that of the bottom sieve of the finest mesh. The purpose of this arrangement will appear hereinafter.

Below Vthe lframe 18 are disposed two vThe sweepings are placed into the top sieve,

and the cover 14 of the box closed to prevent dust, etc., from escaping therefrom. Taking hold of the handle 26, the frame 18 with the sieves thereon is given a shaking or vibrating motion. Due to this motion, the liner material passes through vthe top sieve into the one immediately below theY same, while the coarser parts are held within the top sieve. These coarser parts comprise cloth pieces, large buttons and other matter -which is of a size that is larger than the mesh of the wire screen of the top sieve.V

Small buttons, snap fasteners and material of like size are held within the sieve immediately below the top screen, while beads and similar material collect in the neXt sieve.

. Pins are held within the bottom sieve, Vthe mesh of the screen of which is smaller than the head of a pin. Needles and dust collect in the drawer 31.

After the separation has been affected, the top sieve is taken out of the box and the material therein emptied into the bottom drawer 32. The cloth pieces, paper, etc.,

can then be easily removed from this drawer while the heavier material remains therein. The other sievesv are then taken out of the box one after the other, and the material of each assorted according to color, quality, etc.

,It is to be observed that, while herein a particular number of sieves Ahas been shown,

any other suitable number may be used ac-V cording to the requirements. Attention is also called to the fact that, instead of actuating the sieves by hand, they may be operated by motor power.

l/Vhat I claim is 1. Ina device of the character described,

ving the bottom sieve in positionv thereon,

means carried by the othersieves for maintaining the same immovable in relation to said bottom sievc and each other, and means extending outside of said receptacle for imparting a vibrating motion to said frameV and the sieves thereon. l

2. In a device of the characterdescribed, the combination with a closed receptacle, of a frame oscillatably mounted thereon, a plurality of sieves detachably mounted upon said frame, said sieves being placed one on top of another and provided with screens in their bottoms of gradually decreasing sizes of mesh from the top sieve to the bottom sieve, andmeans for imparting a vibrating motion to said frame and the sieves thereon.

' Signed at New York, in the county of New York and State of New York, this 27 th day of January, A. D. 1919.

CHRISTIAN W'ILDHABER.
